v1.0.5

This release adds stable session identifier telemetry headers to improve observability for forking Apache workers. It also fixes child-scope tracing directive overrides and baggage extraction limits, and updates the underlying Datadog APM C++ Tracer with the latest available improvements.

What's Changed

Functional Changes

• Stable session identifier telemetry headers. All telemetry requests now include DD-Session-ID and, in child processes, DD-Root-Session-ID. #54
• Update underlying Datadog APM C++ Tracer to v2.1.0. #45, #73 and #74

Bug Fixes

• Respect child-scope overrides for tracing directives. Tracing directives configured in nested Apache scopes (e.g. <Location>, <Directory>) now properly override the values inherited from their parent scope. #62
• Baggage limits enforced on extraction. Size and count limits previously applied only on injection now also bound incoming baggage, preventing oversized propagation headers. #73

• Remove sampling delegation.
• Fix RUM configuration inheritance.

Full Changelog: v1.0.3...v1.0.4

v1.0.3

This update addresses an issue where spans were incorrectly marked as erroneous when no tracing context was available for extraction. Additionally, the requirement for glibc has been relaxed to improve compatibility.

What's Changed

• fix: Prevent spans from being set to an error state when tracing context is missing by @dmehala in #12
• feat: Disable tracing on themod_status handler by @dmehala in #13
• chore: log module information (version and product enbaled) by @dmehala in #15

New Contributors

• @dubloom made their first contribution in #10

v1.0.0 - Initial Release

New Features

• Datadog Tracing Integration: This initial release introduces a new module that adds tracing capabilities for Apache HTTP Server. The module by default enables distributed tracing on all requests.

Key Highlights

• Automatic Trace Generation and Context Propagation: The module automatically generates traces for incoming requests, capturing essential contextual information. It also automatically propagate trace context propagate for supported propagation styles - W3C, Datadog and B3
• Remote Configuration: Configure remotely sampling rates or span tags. For more details, visit Datadog's website.

Getting Started

To begin using the new Datadog tracing module for Apache, please refer to the documentation.

Feedback and contributions are welcome as we continue to improve and enhance this module.
